Kernel driver not installed (rc=-1908)

[snowopolis]

I've been using VirtualBox on my Mac 10.6.4 machine without problem. This morning when I launched it I got a dialog with the following error:

Kernel driver not installed (rc=-1908)
Make sure the kernel module has been loaded successfully.


At first I thought my virtual hd was corrupted but all my virtual machines are ending the same way. This dialog comes up really fast.

Anyone else see this?

The only thing I can find that has changed on my Mac is that it took two updates yesterday (8/31/2010).

Snow Leopard Graphics Update 1.0
Security Update 2010-005 1.0

I know VirtualBox was working yesterday before I took these updates. I don't see anyway to revert these updates. Not sure if they're involved or not.

I reinstalled VirtualBox and the app started working again.
